Carogit pipes are usually used in the transfer of sewage and fluids that are transferred by gravity and fluid transfer is designed without internal pressure. Due to the fact that corrugated pipes do not have internal load pressure, it means that the fluid passing through these pipes does not have internal load pressure, and these pipes are practically responsible for transferring liquid fluids as an underground atmosphere. Usually, this type of pipe has a maximum They can withstand internal pressure of 2.5 times. This type of pipe is offered in two types with couplers and without couplers. The size of corrugated pipes is available in the non-coupler type from 200 to 1000 mm and in the coupler type from 200 to 3500 mm.

Double-walled polyethylene pipes or corrugated pipes as you can see in the picture above are called pipes that have two walls, one outer with a wavy appearance or in other words, a ring and an inner layer of the pipe that has a smooth surface that Fluids with acidic and alkaline wastewater and industrial effluents are used. Carogite pipes also have an outer surface which is ring-shaped and has high strength and all surface and subsurface pressures, both live and dead load in They are borne under the ground and the reason for this loop is the curling of the pipe surface due to the strengthening of the pipe. Due to the location of this type of pipe in the dug canals and trenches and the possibility of traffic load on this type of pipes, they are designed in a way that has the ability to bear the weight of soil on the canal and traffic load on it at the same time. . Therefore, these types of pipes have the ability to withstand very high external pressure. Carogit pipes are classified into three compression sections (meaning pressure, external load pressure), which are 16-31 / 5-64 kN, respectively, each of which has a specific consumption in terms of soil surface type, surface and subsurface load pressure. Today, we see corrugated pipes in this way in our world and in everyday life in the streets and alleys with a yellow interior and a black cross section.

Each corrugated pipe has a specific value for torque; For example, the operating pressure in sewage systems is equal to the atmospheric pressure, so the cyclic pressure of these pipes has a moderate limit.

For example, it can be said that 200 mm polyurethane sewage polyethylene pipe has a ring resistance of 5.31 kN and double-walled polyethylene corrugated pipe with a size of 250 mm has a ring resistance of 16, 5.31 and 64 kg. Is Newton. It is interesting to know that pipes with dimensions of 500 mm and above have only a ring pressure of 5.31 kN and are thus designed only for installation in larger projects.

Advantages of Carogit Pipe

The advantages of corrugated pipe in addition to external strength include flexibility, lightness, easy and fast installation, low roughness coefficient, and compliance with environmental standards and its non-toxicity. Other advantages of these pipes include:

• Smooth the inner surface and prevent fouling
• UV resistant
• Fluid transfer
• Excellent sealing by special bell-socket spigot sealing method
• Low installation costs
• High mechanical resistance to external loads
• High chemical resistance against all kinds of gases and corrosive substances

Production methods of corrugated pipe and corrugated spiral pipe

Carogit pipes are produced in different sizes in the form of Carogit pipes and Carogit spiral pipes, which in fact only the production method is different in that in the production of Carogit pipes, polyethylene material is molded and pressed in one piece, but in the production of pipes. Spiral carogit production method is very different. In this method, the profiles or the protrusions on the pipe are cooled by the extruder that produces the pipe profiles after cooling and passing through the water inside the tub, and it is gradually rolled in a spiral and glued together by a series of interactions. After gluing the inner layer of the tube, which is yellow, it sits on the inner wall of the tube and on the profiles and is glued on the tube by defined high pressure pulleys. These pipes are usually produced in high sizes, ie from 1000 to 2500. The sizes of corrugated and spiral corrugated pipes are:

Size of corrugated and spiral corrugated pipes with circular pressure 16 kN, 31.5 kN, 64 kN

110 mm, 125 mm, 160 mm, 200 mm, 250 mm, 315 mm, corrugated pipe 400 mm, 500 mm, 600 mm, 700 mm, 800 mm, 900 mm, 1000 mm, 1200 mm, 1400 mm, 1600 mm, 1800 mm, 2000 mm, 2400 mm, 2500 mm, 3000 mm

Application of corrugated pipe

Carogit pipes are mainly used in water and sewage transmission networks, agricultural water supply and irrigation systems, drainage and power cables in cities and villages.

One of the important applications of corrugated pipes is their use in power cable transmission system. In power pipelines, the working pressure is approximately equal to 16 kN / m2. These pipes have other applications such as construction of manholes, sewage treatment tanks, pipes for transferring water to the sea and rivers, etc. Of course, to make this equipment, Carogit pipes with a very large diameter are needed.

Polyethylene has the necessary properties and long life and meets the human needs in wastewater transfer, which includes the least corrosion by gases and wastewater acids.

Familiarity with carogit pipe standards

All stages of production, storage, installation and commissioning of polyethylene corrugated pipes are performed in accordance with valid industry standards. Many necessary standards are available in this area, some of the most important of which are mentioned in this section.

The global standard for polyethylene pipes and fittings, DIN 16961, is a standard that speaks of the corrugated resistance of corrugated pipes in long-term applications. This standard is designed for burial pipes that are subjected to relatively high pressure. ISO 9969 is used to test the methods of testing the annular pressure of a pipe in the short term.

The circular flexibility of the corrugated pipe is described in EN 1446; According to this reference, changes in the wall of the corrugated pipe against stress, impact, tension, pressure and bending are examined; If the double-walled polyethylene pipe can return to its original shape after environmental stress, it has ideal and standard conditions.

Quality control tests and the method of performing them for corrugated pipe are stated in EN 13476 standard. In general, the minimum annular pressure for a large corrugated pipe is 31.5 kN / m2.

Buying different types of corrugated pipes is cost-effective in every way because it has useful properties and characteristics. Resistance and stability against destructive changes in the environment is the most important advantage of these pipes.

Carogit pipe fittings:

Double-walled fittings are divided into two general categories: Fabricated double-walled fittings and double-walled corrugated pipe fittings for sewage

Custom Carogit Double Wall Fittings (Fabricated)

Custom Carogit double-walled fittings are welded hard according to the customer’s order, and polyethylene double-walled fittings are produced according to German factory and DIN standards.

Fittings for double-walled corrugated pipes for sewage

Easy installation, resistance to compressive and corrosion forces, light weight and reduction of purchase and installation costs of double-walled polyethylene fittings and durability and long service life of this type of fittings have made this type of fittings welcome in sewerage projects. The variety of double-walled polyethylene connections, the development of the water supply network has accelerated the implementation of sewerage projects and increased the quality of its implementation.
